material recovered to date barely exceeds 400,000 years ”, explains Enrico Cappellini, associate professor at the Globe Institute, University of Copenhagen, and principal leader of the group of research. “Now, the analysis of ancient proteins with mass spectrometry, an approach commonly known as paleoproteomics, allows us to overcome these limits,” he adds. Theories about human evolution The fossils analyzed by the researchers were found in 1994 by the team led by Juan Luis Arsuaga, José María Bermúdez de Castro and Eudald Carbonell at stratigraphic level TD6 of the Gran Dolina site, one of the archaeological and paleontological sites of the Sierra de Atapuerca, in Burgos. Initial observations led to the conclusion that Homo ancestor

was the last common ancestor of Neanderthals and modern humans, a conclusion based on the morphology of the fossils. For years, the exact relationship between Homo antecessor and other Peru Phone Number List human groups, such as ourselves and Neanderthals, has been hotly debated among experts. Although the hypothesis that Homo antecessor could be the common ancestor of Neanderthals and modern humans is very difficult to fit into the evolutionary scenario of the genus Homo, the new findings in TD6 and subsequent studies revealed several shared characters among the human species found in Atapuerca and Neanderthals Furthermore, additional studies confirmed that the facial characteristics of Homo antecessor are very similar to

those of Homo sapiens and very different from those of Neanderthals and their more recent ancestors. “I am pleased that the protein study provides evidence for a possible relationship between Homo antecessor, the common ancestor of Neanderthals, modern humans and Denisovans. The characteristics shared by Homo antecessor with these hominids appeared clearly much earlier than previously thought. Therefore, Homo antecessor could be a basal species of emerging humanity that gave rise to Neanderthals, Denisovans and modern humans ”, adds José María Bermúdez de Castro, scientific co-director of the excavations in Atapuerca and corresponding co-author of the article.
